On December 15, 1929, Paul Eluard and Andre Breton published an essay about poetry in the publication La Revolution Surrealiste (the Surrealist Revolution) as a reaction to the publication by poet Paul Valéry « Notes sur la poésie » in Les Nouvelles littéraires of September 28,1929. When Paul Valery wrote "Poetry is a survival", Breton and Éluard made fun of it and wrote : « Poetry is a pipe », as a referral to the painting of Magritte.[12]
